ISSUE:
Getting http://.example.com raises UnicodeError
Attempting to get e.g. `http://.example.com` results in a `UnicodeError`. It seems like the intention so far has been to raise `InvalidUrl` instead (see e.g. [this line](https://github.com/psf/requests/blob/ca6f9af5dba09591007b15a7368bc0f006b7cc50/requests/models.py#L401)).

I see there was some hesitation in fixing a similar issue (#4168) and would like to add that even catching the error just to rethrow as a requests exception would be beneficial.

## Expected Result

Based on PR #774: `InvalidUrl: URL has an invalid label.`

## Actual Result

`UnicodeError: encoding with 'idna' codec failed (UnicodeError: label empty or too long)`

## Reproduction Steps

```python3
import requests
requests.get("http://.example.com")
```

## System Information

    $ python -m requests.help

Requests HTTP Library
~~~~~~~~~~~~~~~~~~~~~

Requests is an HTTP library, written in Python, for human beings.
Basic GET usage:

   >>> import requests
   >>> r = requests.get('https://www.python.org')
   >>> r.status_code
   200
   >>> b'Python is a programming language' in r.content
   True

... or POST:

   >>> payload = dict(key1='value1', key2='value2')
   >>> r = requests.post('https://httpbin.org/post', data=payload)
   >>> print(r.text)
   {
     ...
     "form": {
       "key1": "value1",
       "key2": "value2"
     },
     ...
   }

The other HTTP methods are supported - see `requests.api`. Full documentation
is at <https://requests.readthedocs.io>.
